Abstract

Le dispositif (2) comprend quatre cylindres d'étirage (6, 7, 8, 9), sur lesquels passe le film (5), et auxquels sont associés des cylindres presseurs (13, 21, 26), avec : un premier cylindre d'étirage (6) d'axe fixe (10), un deuxième cylindre d'étirage (7) d'axe fixe (12) décalé par rapport au précédent, un troisième cylindre d'étirage (8) de préférence réglable en position et un quatrième cylindre d'étirage (9) d'axe fixe (25). Ces cylindres (6 à 9) sont entraînés en rotation à des vitesses différenciées, de manière à former un premier étage d'étirage entre le deuxième cylindre (7) et le troisième cylindre (8), de préférence avec une distance d'étirage (D) réglable, et un deuxième étage d'étirage entre le troisième cylindre (8) et le quatrième cylindre (9). L'invention s'applique à l'étirage longitudinal de films synthétiques.
